Why Does the Hero Always Have to Go Down There? The Story Needs Him to Come Back

The pattern is consistent enough to be recognised across cultures that had no contact. A living person travels into the realm of the dead deliberately, usually for a stated purpose, crosses a boundary that is difficult and marked, meets the dead including someone they knew, obtains something or learns something, and returns to the living world changed. The return is essential, since without it the story is simply an account of dying. Almost always a condition is attached to the return, and breaking it costs whatever was gained.

The stated purposes fall into a few groups:

• •To retrieve somebody who has died
• •To obtain knowledge available only from the dead
• •To complete a task set as a trial or punishment
• •To rescue or release those held there
• •To find an object that exists nowhere else
• •Occasionally by accident, having strayed too far

The episode is older than any of the versions usually cited and turns up in the earliest literature we can read. A Sumerian account has the goddess Inanna descend, passing through seven gates and surrendering an item of clothing at each, dying there and being revived only at the cost of a substitute. The Epic of Gilgamesh contains a related journey in search of the secret of survival. The Odyssey has its hero summon the dead at the edge of the world to ask the way home. The Aeneid sends its hero down to meet his father and be shown the future of Rome, which turns the episode into political prophecy.

The rule attached to coming back is the most consistent detail in the whole pattern and it is worth examining on its own. The best known version forbids looking behind on the way out, and the failure that follows is immediate and final. Other versions forbid eating anything below, which binds the eater to the place, or forbid speaking, or set a time limit that turns out to have run differently below than above. What the conditions share is that they are easy to state, impossible to argue with and broken by an ordinary human impulse rather than by weakness, which is what makes the failure land.

The episode survived the end of the belief systems that produced it, which suggests it is doing something structural. It supplies a way to deliver information no living character could have, which is useful to any storyteller. It stages an irreversible loss as something a character actively confronts rather than merely suffers. It marks a decisive change in a character by requiring passage through a boundary and back. Modern versions keep the shape while replacing the underworld with a coma, a wilderness, a prison or a descent into a city's depths, and the conditional return survives intact, usually as a rule about not looking back.

A living traveller crosses into the land of the dead deliberately, obtains knowledge or a person, and returns under a condition whose breach costs everything. The pattern predates the familiar Greek versions, appearing in Sumerian and Babylonian literature. It persists because it delivers otherwise impossible information and stages irreversible loss as something confronted rather than suffered.
